HMRouter的页面生命周期还有好的获取办法吗？

// 定义注解 
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface OnPageLifecycle {
    HMLifecycleState state();
}
 
// 在页面中使用 
export default struct HomePage {
    @OnPageLifecycle(state = HMLifecycleState.onHidden) 
    private handlePageHide() {
        this.isOnShowPage  = false;
    }
}

abstract class BaseRouterPage implements IHMLifecycleAware {
    constructor() {
        HMRouterMgr.bindLifecycle(this); 
    }
 
    // 子类覆盖需要的方法 
    onPageShow(): void {}
    onPageHide(): void {}
}

@Entry 
struct DetailPage extends BaseRouterPage {
    override onPageHide() {
        this.cancelRequests(); 
    }
}

class LifecycleProxyInterceptor implements RouterInterceptor {
    postHandle(request: RouterRequest, response: RouterResponse) {
        const owner = response.context  as Component;
        owner.addObserver(HMLifecycleState.onAppear,  () => {
            EventBus.emit('PAGE_VISIBILITY_CHANGE',  {visible: true});
        });
    }
}
 
// 注册拦截器 
HMRouterMgr.addInterceptor(new  LifecycleProxyInterceptor());

// 扩展HMRouterMgr方法 
function HMRouterMgr.observeLifecycle(state:  HMLifecycleState, callback: () => void) {
    this.getCurrentLifecycleOwner()?.addObserver(state,  callback);
}
 
// 调用端简化 
HMRouterMgr.observeLifecycle(HMLifecycleState.onHidden,  () => {
    this.releaseResources(); 
});

@Entry 
struct UserPage {
    @State @Watch('onVisibilityChange') 
    isActive: boolean = false;
 
    private onVisibilityChange(newVal: boolean) {
        if (!newVal) this.cleanup(); 
    }
}

const lifecycleHandlers = new Map<HMLifecycleState, Function>([
    [HMLifecycleState.onAppear, () => Analytics.trackPageShow()], 
    [HMLifecycleState.onDisappear, () => Analytics.trackPageHide()] 
]);
 
// 统一注册入口 
HMRouterMgr.getRouterLifecycleRegistry().setGlobalHandlers(lifecycleHandlers);

@Component 
struct SmartLifecycleView {
    @Link @StorageProp('currentPageState') 
    pageState: HMLifecycleState;

    aboutToDisappear() {
        this.pageState  = HMLifecycleState.onDisappear; 
    }
}

// 处理快速切换场景 
let pendingTask: number | null = null;
function handleFlicker() {
    if (pendingTask) clearTimeout(pendingTask);
    pendingTask = setTimeout(() => {
        // 实际业务逻辑 
    }, 300);
}
